• fermentation

• electron transport chain

• the Krebs cycle

Dorion decides one day to run a marathon without any training. Halfway through the race, he begins to feel pain in his thighs. He is also breathing very rapidly. What is causing the pain in Dorion's legs?

• The weather must have been too hot to run.

• Too much oxygen was getting to the cells, causing them to cramp.

• The build-up of carbon dioxide caused the muscles to begin cramping.

• Lactic acid built up in his muscles causing the pain.
